UFC officials confirmed the winner could be in position for a shot at the 145-pound championship.

UFC 155 takes place Dec. 29 at MGM Grand Garden Arena in Las Vegas. The main event is a heavyweight title fight and rematch between champion Junior Dos Santos and ex-titleholder Cain Velasquez, which headlines the pay-per-view portion of the show.

FX and Facebook are expected to carry the prelims, likely including the Koch vs. Lamas bout.

Koch was scheduled to meet champion Jose Aldo (21-1 MMA, 3-0 UFC) at UFC 153 earlier this month. But a Koch injury forced him off the card, and former lightweight champion Frankie Edgar, dropping down a weight class, was set to fight for the title. But then Aldo, too, was hurt, and the fight was canceled.

Also and Edgar are still expected to fight at a future date, and the Koch vs. Lamas winner could be up next.

Koch most recently fought in September 2011, when he beat “The Ultimate Fighter 12″ winner Jonathan Brookins by unanimous decision at UFC Fight Night 25, which made him 2-0 in the UFC. Since his lone pro loss to Chad Mendes at WEC 47, Koch is 4-0.

Lamas is coming off a unanimous-decision win over Hatsu Hioki at UFC on FX 4 in June. The upset of the Japanese fighter (whom many considered No. 2 in the world) moved Lamas to 3-0 in the UFC. Before the win over Hioki, Lamas had a “Submission of the Night” win over Cub Swanson at UFC on FOX 1 and a knockout victory over Matt Grice in June 2011.
